Struct indicatif::MultiProgress

pub struct MultiProgress { /* private fields */ }

Manages multiple progress bars from different threads

Implementations

impl MultiProgress

pub fn new() -> Self

Creates a new multi progress object.

Progress bars added to this object by default draw directly to stderr, and refresh a maximum of 15 times a second. To change the refresh rate set the draw target to one with a different refresh rate.

pub fn with_draw_target(draw_target: ProgressDrawTarget) -> Self

Creates a new multi progress object with the given draw target.

pub fn set_draw_target(&self, target: ProgressDrawTarget)

Sets a different draw target for the multiprogress bar.

pub fn set_move_cursor(&self, move_cursor: bool)

Set whether we should try to move the cursor when possible instead of clearing lines.

This can reduce flickering, but do not enable it if you intend to change the number of progress bars.

pub fn set_alignment(&self, alignment: MultiProgressAlignment)

Set alignment flag

pub fn add(&self, pb: ProgressBar) -> ProgressBar

Adds a progress bar.

The progress bar added will have the draw target changed to a remote draw target that is intercepted by the multi progress object overriding custom ProgressDrawTarget settings.

Adding a progress bar that is already a member of the MultiProgress will have no effect.

pub fn insert(&self, index: usize, pb: ProgressBar) -> ProgressBar

Inserts a progress bar.

The progress bar inserted at position index will have the draw target changed to a remote draw target that is intercepted by the multi progress object overriding custom ProgressDrawTarget settings.

If index >= MultiProgressState::objects.len(), the progress bar is added to the end of the list.

Inserting a progress bar that is already a member of the MultiProgress will have no effect.

pub fn insert_from_back(&self, index: usize, pb: ProgressBar) -> ProgressBar

Inserts a progress bar from the back.

The progress bar inserted at position MultiProgressState::objects.len() - index will have the draw target changed to a remote draw target that is intercepted by the multi progress object overriding custom ProgressDrawTarget settings.

If index >= MultiProgressState::objects.len(), the progress bar is added to the start of the list.

Inserting a progress bar that is already a member of the MultiProgress will have no effect.

pub fn insert_before( &self, before: &ProgressBar, pb: ProgressBar ) -> ProgressBar

Inserts a progress bar before an existing one.

The progress bar added will have the draw target changed to a remote draw target that is intercepted by the multi progress object overriding custom ProgressDrawTarget settings.

Inserting a progress bar that is already a member of the MultiProgress will have no effect.

pub fn insert_after(&self, after: &ProgressBar, pb: ProgressBar) -> ProgressBar

Inserts a progress bar after an existing one.

The progress bar added will have the draw target changed to a remote draw target that is intercepted by the multi progress object overriding custom ProgressDrawTarget settings.

Inserting a progress bar that is already a member of the MultiProgress will have no effect.

pub fn remove(&self, pb: &ProgressBar)

Removes a progress bar.

The progress bar is removed only if it was previously inserted or added by the methods MultiProgress::insert or MultiProgress::add. If the passed progress bar does not satisfy the condition above, the remove method does nothing.

pub fn println<I: AsRef<str>>(&self, msg: I) -> Result<()>

Print a log line above all progress bars in the MultiProgress

If the draw target is hidden (e.g. when standard output is not a terminal), println() will not do anything.

pub fn suspend<F: FnOnce() -> R, R>(&self, f: F) -> R

Hide all progress bars temporarily, execute f, then redraw the MultiProgress

Executes ‘f’ even if the draw target is hidden.

Useful for external code that writes to the standard output.

Note: The internal lock is held while f is executed. Other threads trying to print anything on the progress bar will be blocked until f finishes. Therefore, it is recommended to avoid long-running operations in f.

pub fn clear(&self) -> Result<()>

pub fn is_hidden(&self) -> bool
